Spray canister

摘要

A trigger-actuated cleaning device dispenses an aerosol cleaning agent from a pressurized canister. The canister has a female valve assembly. In one form an over cap fits onto the canister over the valve and has a male stem on a pivotable part of the over cap that opens the valve when moved by a rod linked to a remote trigger. The stem is either formed integrally with the over cap or is removably attached to a stem socket formed in the over cap. In another form the actuator is a button having a stem that fits in the female valve.
